模块,用一砣代码实现了某个功能的代码集合。 类似于函数式编程和面向过程编程,函数式编程则完成一个功能,其他代码用来调用即可,提供了代码的重用性和代码间的耦合。而对于一个复杂的功能来,可能需要多个函数才能完成(函数又可以在不同的.py文件中),n个 .py 文件组成的代码集合就称为模块。 如:os 是系统相关的...
As part of this change, the 安装Python 模块 and 分发Python 模块 sections of the documentation have been completely redesigned as short getting started and FAQ documents. Most packaging documentation has now been moved out to the Python Packaging Authority maintained Python Packaging User Guide and th...
For example, py-up and py-down go up or down one Python stack frame, which usually corresponds to several C stack frames. py-print prints the value of a Python variable, and py-bt prints the Python stack trace. (Added as a result of bpo-8032.) If you use the .gdbinit file ...
We all know things can go wrong when writing programs. Syntax errors, spelling mistakes, even forgotten sections of code; it's all possible. Sometimes, issue...
Sections support any reStructuredText formatting, including literal blocks:: $ python example_google.py Section breaks are created by resuming unindented text. Section breaks are also implicitly created anytime a new section starts. """ 不要在文档注释复制函数定义原型, 而是具体描述其具体内容, 解释...
得到的计算结果不是布尔类型,而是数字99,这是为什么呢? 因为Python把0、空字符串和None看成是False,其他数值和非空字符串都看成True True and 0计算结果是0 继续计算0 or 99计算结果是99。因此结果是99 not计算的优先级是高于and和or的 True and not False # ==> True ...
